The great tone and smooth playability of the LL6 are due to Yamaha's never-ending search for perfection. The recently developed A.R.E. (Acoustic Resonance Enhancement) process gives your guitar a broken-in and aged tone. By controlling the atmospheric pressure, temperature, and humidity, the molecular properties of the wood are manipulated to mirror those of a guitar that has been played for years. Each L Series guitar also sports a modified non-scalloped bracing that enhances the guitar's low end. And the 5-ply mahogany/rosewood neck, after re-evaluation of string height and spacing, has a new design for improved playability. The Yamaha LL6 utilizes newly developed advances in guitar construction to bring you an amazingly playable and great-sounding instrument.
